Good morning. And welcome to "this week." 100 days. Maybe I should just pack up and go home. The president faces tough questions. The rumors, a little exaggerated. How does he fight the lame duck label? Is the problem congressional leadership or obstruction? Then, the oracle of omaha. As the dow nears 15,000, the world's best investor is here in a "this week" exclusive. James carville and mary matalin joins our powerhouse roundtable. Jason collins makes history. You know the sky is blue. But you keep telling yourself it's red. And whoopi goldberg shines in our "sunday spotlight." Hello again. A packed show this sunday morning. We begin with breaking news from the middle east. For the second day in a row, israeli war planes have hit syria. A series of large explosions in damascus. Abc's alex marquardt has the latest from jerusalem. Alex, I know the israelis aren't saying much. But the target, apparently iranian missiles that could be used to target israel. Reporter: Good morning, george. That is reportedly one of the targets. Israeli officials aren't saying which, of course, is pretty much standard operating procedure after something like this. Just moments ago, they say they struck three targets. An airport, and what is believed to be an arms depot on a mountain that overlooks damascus. If confirmed by israel, this would be the second set of air strikes inside syria, in the past few days, in the past 48 hours. On the night, from thursday to friday, israel believes they have targeted a shipment of long-range, iranian-made, missiles bound for the militant group hezbollah. Syria has made a statement, accusing israel, of collating with wha call an al qaeda-linked group. They say that israel aims to give direct military support to terrorist groups. Now, israel has long warned they will not allow advanced weaponry, specifically chemical weapons, from ending up in the hands of its enemies. That's what appears to be happening here. An iranian military official, the top official, said that hezbollah will respond to the israeli strikes. It's hard to know if that's bluster or a genuine threat. As you can imagine, tensions here are very high. Israel has moved two of its famous iron dome anti-missile batteries into the north, near the borders with syria and lebanon, to cover whatever could come on from there. Not just on to the civilian population. But also on to what be strategic military targets. We're also getting reports that syria's regime has held an emergency meeting to figure out what its response should be. Perhaps in a sign that israel doesn't think that a response could be imminent, prime minister benjamin netanyahu is proceeding with a trip to china later tonight. Alex, thanks. Let's bring in our roundtable. Cokie roberts from abc. Bill richardson. AND jim DeMint, founder of the heritage foundation. And james carville and mary matalin. Let me go to you. You were serving as the u.N. Ambassador. The president, ruled out putting u.S. Boots on the ground in syria. But the pressure is building for more military action. Yes. And I think he signaled that he's ready to use military action. We can't have boots on the ground. But I think potentially, some kind of option like air strikes, against some of those weapon sites are in the cards, in my view. And israel is sending a signal to iran, to hezbollah, and possibly to us, too, that the situation is getting very tense. But I think in the next few days, my view, is that the president will opt towards some kind of limited military option. senator DeMint, is that something he should do? Israel is acting in self-defense. Clearly, iran is shipping more precise-guided missiles through syria. The less stable it is, the more dangerous it is for israel. I think we've probably taken too much of a passive or at least an unclear stance on this for too long, that's created more instability. I think the president needs to make it clear what we will do. And he's tried to do that with his bright, red line, which he hasn't followed through on. I don't know what his steps should be right now. But clearly, his indecisiveness has destabilized and probably brought israel into this. Clearly, also, cokie, the public not rushing to react. And that is a huge problem. The president doesn't know what to do. And neither does anybody else. You have a lot of people criticizing the president for doing nothing. And you ask them what should happen, they kind of dance all over the place. But with the public being so completely disillusioned with american wars abroad that have gone on for so long. These wars in afghanistan and iraq have cost every american family something like $45,000, not to mention, of course, the lives. And it really takes a whole foreign policy option off the table when americans say that they don't want to have our troops engaged in another war. And that's a problem because we need to have every, single option available in a very dangerous world. One of the big questions, mary matalin, is how effective actually arming the rebels can be. And what kind of consequences that can create if the weapons fall into the wrong hands. That's right. To echo much of what has been said here, policy ranges from incoherent to feckless. He's redrawn his red line. He's reversed his opposition to arming the rebels. He doesn't know who they are. We don't have good intelligence because of the effects of the policies, his policies, dismantling our security infrastructure. Yes, it is difficult to know what to do in a transitioning region. Something we know not to do is what he has h is issue these red, bright lines. And then, walk back from them. It's the parental thing. Every parent -- I don't normally do that. I will play george will here. Talking about dithering. He and I don't agree a lot. But we are the pro dithers. And you talk about helping the rebels, you have to understand this is not patrick henry and benjamin franklin we're dealing with. And it is not altogether certain, the first worst in the world is the rebels and the second is the government. It's not like we have a great choice over there. That's true. It's a terrible set of choices. And nobody really does know what to do. But what does seem to be happening is there's a lot of disillusion with the united states in the muslim world. And that's a problem. It is. What I see, I saw a signal by general edris, who is the head of the rebels and the military council. And he renounced al qaeda. I know there's questions -- that clears it up. Yeah. Britain and france are going to start arming the rebels, i think that's a signal that some -- I won't say cover. But it's a move in the direction of nato and the president moving. And we're not going to go in alone. And refugees. We have got to do a whole lot more to address that. The issue here and syria's almost a distraction here. The weapons moving through syria because it's completely destabilized. We have to focus on how we can demonstrate our support of israel and continue the pressure on iran. Otherwise, we're going to create more problems inside syria. That's the point. If my geography is correct. For weapons to get from iran to syria, they have to go through iraq. Overfly. If we had better allies in iraq -- if we had better allies in general. This president is going to reset our relationship with russia. That would put pressure on assad. And reset all of the relationships in the world to leverage power to bring peace. And none of that has come. Iran is the real issue. Weapons have passed through syria to iran. And will continue to because we don't follow-up on anything we say we're going to do. There are not good options. But weak promises and provocation.
